It's Cinco de Mayo, and we're ready for happy hour! We whipped up some super spicy Jalapeño margaritas (shown in our Houston Hometown Glassware.)
Slice jalapeño, and remove most seeds. Muddle the jalapeño in a cocktail shaker. Fill with ice, and add all ingredients minus the garnish. Shake well, and strain into glass over ice. Garnish with jalapeño slice.
